A halo of light?

In the previous post, I said that even grey days have their charm. Here is some proof from yesterday which was both frosty and foggy. 
 
In the vineyard

This is the field behind the house, used in part as a vineyard farmed organically – hence the lovely long grass.

 
To my eye this scene was much whiter and more wintry than it appears in the picture, but that may just be my eyes. After all, the camera is much younger than I am.
 

 
On top of the hill

Here I am on top of the hill behind the house where three beech trees stand in a line, perhaps the remains of a hedge. This is two of them. 

 

Am I dreaming or is there a halo of light around both trees?

It's interesting that the pictures have come out in different colours. In the first one I'm facing west and in the second north. In this case the camera is more sensitive than I am, because I hadn't noticed any difference.
